Blown head gasket? Or any ideas please
My 04 silverado just hit $100,000 miles. Had for 3
years still paying on it.. I always keep up on
Maintenance, oil changes etc. When I start it
sometimes it has a loud rattling noise,sounding
like its coming from top of engine. Noticed my
water reservoir was really low , I would fill and it
would be gone pretty quick. Also condensation on
the lid of my oil lid, and when I checked oil it had a
little gunk on the stick. Immediately got an oil
change. Thought it was ok but yet again noise,
water etc. Now when I check my dip stick it looks
ok but just a little runny. Also at times it will loose
oil pressure at idle. Please help!
